A Brooklyn councilman has backed the renaming of a borough street honoring a notorious anti-Semite and rechristening it with a more deserving namesake.

Corbin Place in Brighton Beach was named after 19th-century robber baron Austin Corbin, father of the Long Island Rail Road and an open anti-Semite. The onetime secretary of the American Society for the Suppression of Jews often used the word “exterminate” in relation to Jewish Americans.

His half-mile-long street will still be called “Corbin Place” — but now after early patriot Margaret Corbin, who fought in the Battle of Fort Washington, in 1776, said City Councilman Chaim Deutsch (D-Sheepshead Bay).

The lawmaker said he’s got the backing of the local community council and the full City Council.

The only cost will be the posting of a smaller street sign for “Margaret Corbin Pl” under one of the current “Corbin Place” markers. A ceremony is set for next month, Deutsch said.

“As a son of Holocaust survivors, I am eager to utilize this opportunity to publicly reject the hatred that Austin Corbin spewed,” Deutsch said.

“With this symbolic street rededication, we are recognizing the contributions of a far more deserving Corbin, the first woman who ever fought for this country in the US military.”
